Leukemia is a cancer of the blood cells, and typically starts in blood-forming tissue, such as bone marrow.

There are many different leukemia types and the names usually come from the cell they affect. These cancers include chronic lymphocytic leukemia (CLL), among others. At Merck, we’re committed to developing treatments that can help improve the lives of leukemia patients.

There is a lot to consider when deciding whether to participate in a clinical trial. Any clinical trial includes risks, which the study doctor will review with you. Make sure you understand the risks before participating.
